Checking user information

The CyberApp must check the information about the authenticated user by sending a GET request to the https://cloud.acronis.com/api/idp/v1/userinfo endpoint with the access token.
The endpoint will respond with:
{
    "sub": "<user_id>",
    // `profile` claim
    "name": "",
    "family_name": "",
    "given_name": "",
    "locale": "",
    "updated_at": "",
    "preferred_username": "",
    "website": "",
    // `email` claim
    "email": "",
    "email_verified": false,
    // `address` claim
    "address": "",
    // `phone` claim
    "phone_number": "",
    "phone_number_verified": false,
    // `roles` claim
    "roles": [
        {
            "role_id": "<role>"
            "rn": "<rn>"
            "rp": "<rp>"
        },
        "..."
    ]
    // `tenants` claim
    // Outputs the list of parent tenant UUIDs up the hierarchy, including only those tenants that have the CyberApp enabled.
    // Excludes tenants with kind 'unit' and 'folder'.
    "tenants": [
        "<parent_tenant_uuid>",
        "<parent_of_parent_tenant_uuid>",
    ]
        "..."
}
